skew를 고려한 전자식 조향장치용 브러시리스 전동기의 파라미터 산정 

Abstract

This paper presents the method to calculate motor parameters considering skew in EPS Brushless motor. Skew is applied to stator or rotor by general technology used for design of reducing noise and vibration in motor. Motor characteristics analysis by using 3D finite element analysis (FEA) is a very time-consuming to perform. Besides, The reliability lacks due to the considerable change of motor characteristics according to the number of elements in 3D FEA. However, analysis time and effort can be saved by characteristic analysis considering skew using 2D-FEA. Therefore, in this paper, a quick and accurate method for the calculations of motor parameters considering skew is suggested. The proposed method is verified by the comparison of calculated and experimental results.
